“Football is a game to be enjoyed by everyone and we shouldn’t accept any form of discrimination that will put our game in shame.

“I hope the football federations all over the world react strongly on all cases of discrimination!

“Social media platforms (Instagram, Twitter, Facebook) need to work better as well with football clubs because every day you see at least a racist comment under a post of a person of colour.

“We’ve been saying it for years and still no action.

“Ladies and gentlemen it’s 2019. Instead of going forward we’re going backwards and I think as players we need [to] unify and make a statement on this matter to keep this game clean and enjoyable for everyone.”

Meanwhile, Cagliari have vowed to identify and ban individuals who did racist chanting on Lukaku.

A club statement read: “The Club underlines – once again – its intention to identify, isolate and ban those ignorant individuals whose shameful actions and behaviours are completely against those values that Cagliari Calcio strongly promotes in all their initiatives. Every single day.

“Cagliari Calcio does not want to underplay what occurred last night, endorses the respectable moral values of its people from all the stadium sections, but firmly rejects the outrageous charge and silly stereotypes addressed to Cagliari supporters and the Sardinian people, which are absolutely unacceptable.
